Having a reserved bit means that the server is not following the protocol correctly. During handshake, the client and the server must negotiate any extensions before they can use them. My guess is that whatever server software you are connecting to is using a sub-protocol without agreeing with the client (perhaps it is assuming that you are using compression).

Without a capture or more information about the server, it is not possible for me to figure out what is going on. For more information on how to capture network traffic, dig into tcpdump.

Or try sudo tcpdump -s 0 -w somefile.cap port <WebSocketPort> to capture everything on the websocket port to a file. (Some adjustments to that command may be required depending on your system).

This file will contain the server addresses and related information that you may not want to post. Unfortunately, I do not have a telegram, but I do have email.

@NabiKAZ What browser are you using on what OS? Can you post code examples to reproduce this?

from rfc6455.

NabiKAZ commented on July 18, 2024

@mbonneau Thanks for response.

As I said, The code is default example:

<?php

require __DIR__ . '/vendor/autoload.php';

$loop = React\EventLoop\Factory::create();

$connector = new Ratchet\Client\Connector($loop);

$connector('ws://................................', [], [.............................])

->then(function(Ratchet\Client\WebSocket $conn) {
	$conn->on('message', function(\Ratchet\RFC6455\Messaging\MessageInterface $msg) use ($conn) {
		echo "Received: {$msg}\n";
		//$conn->close();
	});

	$conn->on('close', function($code = null, $reason = null) {
		echo "Connection closed ({$code} - {$reason})\n";
	});

	$conn->send('hello');
}, function(\Exception $e) use ($loop) {
	echo "Could not connect: {$e->getMessage()}\n";
	$loop->stop();
});

$loop->run();

"hello" message was sent, but didn't received any replay data, and so closed connection!

But this code don't have any problem in send and received data:

<html>
<head>
<title>WebSocket</title>

<style>
 html,body{font:normal 0.9em arial,helvetica;}
 #log {width:1200px; height:500px; border:1px solid #7F9DB9; overflow:auto;}
 #msg {width:330px;}
</style>

<script>
var socket;

function connect(){
  var host = $("server").value;
  try{
    socket = new WebSocket(host);
    log('WebSocket - status '+socket.readyState);

    socket.onopen    = function(msg){ log("Welcome - status "+this.readyState); };
    socket.onmessage = function(msg){ log("Received: "+msg.data); };
    socket.onclose   = function(msg){ log("Disconnected - status "+this.readyState); };
  }
  catch(ex){ log(ex); }
  $("msg").focus();
}

function send(){
  var txt,msg;
  txt = $("msg");
  msg = txt.value;
  if(!msg){ alert("Message can not be empty"); return; }
  txt.value="";
  txt.focus();
  try{ socket.send(msg); log('Sent: '+msg); } catch(ex){ log(ex); }
}
function quit(){
  log("Goodbye!");
  socket.close();
  socket=null;
}

// Utilities
function $(id){ return document.getElementById(id); }
function log(msg){ $("log").innerHTML+="\n"+msg; }
function onkey(event){ if(event.keyCode==13){ send(); } }
</script>

</head>
<body>
<h3>WebSocket v2.00</h3>
 <input id="server" size="50"><button onclick="connect()">Connect</button>
 <div id="log"></div>
 <input id="msg" type="textbox" onkeypress="onkey(event)"/>
 <button onclick="send()">Send</button>
 <button onclick="quit()">Quit</button>
</body>
</html>

What browser are you connecting with? Any other info (request and response headers on the websocket connection and a packet capture if possible) would be helpful.

I use Version 69.0.3497.100 (Official Build) (64-bit) But as I said this problem is on CLI PHP and don't dependency with browser.
I don't know how to do: request and response headers on the websocket connection and a packet capture if possible.

I think the server is a special kind!
I can not leave my address here. If you have a telegram to send to you?

NabiKAZ commented on July 18, 2024

Ok, Please send me your email.

NabiKAZ commented on July 18, 2024

Oops! You pointed to the right compression issue. The problem was this: 'Sec-WebSocket-Extensions' => 'permessage-deflate', and the problem was resolved by remove it.
Thank you very much. 😍

But how can one keep it and solve the problem in principle? I tested with PHP 7.2.4, but there is still a problem with permessage-deflate.

The permessage-deflate branch has been merged into master and tagged.
